Summary:
Horizontal drilling is used to install pipes for cables etc under obstacles such as buildings, rivers, roads etc. The drilling operation can be considerably delayed if the depth of drilling is chosen to coincide with underground structures with high drilling resilience. Consequently it is advantageous to perform a pre-drilling survey in order to determine the optimum depth of the pipe.
Resistivity mapping can be successfully applied in order to accomplish this as is shown by the present case story for the Advanced Geosciences STING/Swift system.

Results:
At this site there was already a horizontal hole drilled and during that operation extra time had been spent penetrating several gravel beds. The client wanted to investigate a method that allowed him to select an optimum depth before drilling. As can be seen in the figure it would have been better to drill 4 meters closer to the surface where most of the gravel could have been avoided.

The data were automatically acquired by the Sting/Swift system and inverted using the RES2DINV software package (avaliable from AGI). For presentation the inverted data were imported into Surfer for Windows where the report above was prepared.

The importance of groundwater can’t be overstated.
It’s crucial for life across the globe, and, in the developing world, access to groundwater is at a premium. However, with resistivity imaging groundwater exploration techniques, even when you’re in one of the driest locations on Earth, deep groundwater is possible to locate.
In 2006, our client, the Engineers Brigade of the Ministry of Defence in Thika, Kenya, used AGI tools and software to locate groundwater at 600 meters deep. While the...

Why groundwater exploration?
This workshop’s purpose was important: As water—especially groundwater—becomes more and more scarce (and thus, valuable) knowing exactly where and how to find it will become more crucial. By training students how to use our resistivity meter for groundwater exploration, we’re...

AGI’s Multi-Electrode Switch Box is an accessory to the SuperSting Wi-Fi. It allows the SuperSting Wi-Fi to automatically control and switch passive electrodes connected by a passive multi-electrode cable for automatic data acquisition in 2D, 3D, and 4D surveys. The rugged and sealed design makes it ideal for harsh environments like sub-surface, marine and borehole measurements, and long-term monitoring systems.
The Multi-Electrode switch box is also available with banana socket connector for each electrode...
